ION MEMORIZATION LIST
Directions: Memorize this list of ions. It is important that you memorize the ions exactly AS THEY ARE TYPED. This includes capital or lowercase
letters, subscripts, +/- charge, and magnitude of charge (superscript numbers). The spelling of the ion name must also be exactly correct. Even a one letter
difference means the difference between sulfate (SO42-) and sulfite (SO32-). Look for patterns to make memorization easier.
You must understand these terms:
MONATOMIC ION = single atom with a charge.
POLYATOMIC ION = group of atoms with a charge.
